TUBING FOR TIRES FOR MOTOR-VEHCLES.

T0 all whom it may concern Be it known that I, JOHN L. DABADm, a citizen of theUnited States, residing at Angels Camp, county of Calaveras,'State of California, have invented certain new and useful Improvements in Tubing for Tires for lVlotor-Vehicles;` and I do declare the following to be a clear, full, and exact description of thesame, such as will enableothers skilledfin the art to which it `appertains to make and use the same, refer- .ence being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates toiinprovements in tires for motor vehicles and is adapted to provide an innerl tubing `for the outer casings of said tires which will not necessitate -the use of air to give the necessary resiliency or cushion effect of pneumatic tires, but at the same time will give the resiliency7 equal to or greater than that of air and which will take up and compensate for all the jolts or jars encountered on the rcads surface. This structure will do away with the objectionable features of pneumatic tires such as blow-outs, punctures, the necessity' of iniiating the same and all the other numerous incidents to the use of such pneumatic tires.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly eiiective for the purposes for which it is de signed.`

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal` of the following specification and claims.

On the drawings similar characters of .reference indicate corresponding parts in the several views.

Figure 1 is a sectional view of a portion of my improved inner tubing. Fig. 2 is a cross sectional View of the inner tubing shown within the outer casing. Fig. 3 is a 'longitudinal section of a portion of the inner tubing showing the mechanism for expanding the saine against the outer casing. F 4 is a top planwiew of the structure shown in Fig. 3 with the spring and casing removed. Fig. 5 is a side elevation of my improved structure partly broken out showing the inner tubing prior to expansion.

Referring now more particularly to the characters of reference on the drawings, the

Specication of Letters Patent. Application led March 20, 1913. Serial 11a-755,620.

numeral 1 designates the telly of a wheel and the numeral 2 the casing adapted to ref ceive my improved inner tubing, which vouter casingis of the saine design asthose now ordinarily used on all pneumatic tires now on the market, in all sizes, no special casing being required. In providing my improved inner tubing I form the same of sheet steel divided into sections, each section comprising an upper member 3 and av lower member 4. Each of the members 3 and 4 is provided with cross braces 3 and 4i respectively to prevent any tendency of these members 3 and 4 to bulge laterally. The upper members of every other section are provided at each end with castings or plates 5 and the corresponding lower members with castings Yor plates G, which castings or plates 5 and 6- are riveted to their respective members and adapted to slidably project into the adjacent members of the intermediate section and not fastened thereto, such intermediate section being then held normally in position by means of a. plurality of springs 7, two of said springs crossing permits the said sections to be moved slid ably apart but still be held in position relative to the plates 5 and 6.

Each of the plates 5 is provided with a fixed receptacle 8. Mounted yon threaded pins 12 are similar recessed receptacles 10. A spring 11 is interposedv between each pair of the receptacles 8 and 10, the pin 12 projecting through the 'central parts of the springs 11. The lower end of the pin 12 is then journaled in a member 13 on the plate 6 and mounted on the same is a worm gear 14, which worm gear is intermeshed with another worm gear 15 mounted on a shaft 16 journaled in members 17 on the plate 6.'

On each end of the shaft 16 isv a universal joint 18, each pair of universal joints on each section being then connected by pins 19 with corresponding orV similar universal joints on the next section and then, this same structure 'is repeated continuously around the ent-ire tubing.

As will beseen, the upper series of the members 3 are capable of movement vertically with respect to the lower series 4 and the springs 11 being interposed between the same give the necessary resiliency. The adjacent members on each section are capable of moving circumferentially with respect to each other and are given a resiliency and are held together by the springs 7. The whole is then held together in close contact with the outer casing 2 and Within the same gear 22 intermeshing With a Worm gear 23' on one ofthe shafts 16. Hence, by turning the pin 20, this turns the Worm gear 22, the Worm gear. 23 and shaft 16 which, by means of the universal joints and connections just described, turns all 0i' the shaftsfl4 in the entire tubing. Incidentally this turns all of the worm gears 15 and all of the Worm gears 16, which turns all. of the pins l2 and since said pins are threaded through the members 10 this causes the members l0 to move up- Wardly and compress the springs 1l.- The tension of such springs Will then tend to force the members 3 and d outwardly and circumferentially and will cause the same to engage the inside of the casing 2 in a strong frictional grip.-

-V This structure makes the complete tire for the Wheel of the vehicle and as will be readily seen it provides a resiliency Within an outer casing similar to the inner pneumatic tubing, but stripped of all the objections to be noted in the use of such pneumatic tubing. For the purpose of taking the tire down, the above described operation would of course be reversed. To permit of the separating operation above described, the pins '19 are, oif course, square'and are Iixed rigidly to one of the universal joints as at 19 and are slidably Vdisposed Within the other.

From the foregoing description it `Will be readily seen that I have produced such ae device as substantially fuliils the objects of the invention as set forth herein. `Wl1ile this specification sets forth in de- 1,1 isser each section consisting of two parts, said sections being adapted to be suitably joined, a turnable pin on one part of each section, a screw member mounted on said pin, a resilient member disposed between said member on said pin and the other part of said section, a pinion. on said turna-ble pin, a Worm gear engaging said pinion, a pin connected With said worm gear, a pinion on said pin, a Worm gear engaging said last named pinion, and a pin on said last named Worm gear projecting outside ot' said tubing, as described.

2. A device ot' the cha 'acter described comprising a tubing consisting of sections,

each section consist-ing of two parts, said sections being adapted to be suitably joined, a turnable pinon one part of each section, a screw member mounted on said pin, a resilient member disposed between said member on said pin and the other part of said section, a pinion oir said .turnable pin, a Worm gear engaging said pinion, a pin on each of said' Worm gears, universal joints connecting all. of said last named pins withn in the tubing, and an operating means for turning one of said last named pins, as described.

In testimony whereof l affix my signature in presence of two Witnesses.
